It might help if you narrowed things down a *bit* also it's not exactly clear, I can't tell whether you would rule out something like Hoover Dam since it is definitely off-Strip, but it's not outside regular mainstream tourist interest.

If you like outdoorsy stuff, Red Rock Canyon or Valley of Fire.

meta: wonder if it's worth merging/compiling a list of these and/or adding to http://www.flyertalk.com/forum/las-v...gas-forum.html (I see there's a hiking thread which would cover the above two parks I mentioned, but I meant in general...)
